Byerly designed the shape of the AR-1 wakeboard to be fast, poppy, and extremely durable. This was accomplished by fusing top and bottom fiberglass laminates in four zones throughout the core. By connecting the top and bottom, a strong I-beam bond is formed. This allows the shape to remain thin with no loss of strength. Board utilizes a continuous rocker to generate maximum speed into the wake with no loss of pop. The result is a wakeboard with a responsive feel and strong edge hold into the wake.
